摘要
威海市是胶东地区温泉资源比较丰富的地区,而研究温泉与断裂及地震活动性的关系具有非常重要的意义。宝泉汤温泉位于市区的东部,是一种富含各种微量元素、矿化度较高的地热水,水化学分析表明,温泉水属于Cl-Na.Ca型;温泉受NW向神道口断裂和近EW向城南河断裂的控制,大气降水和海水顺着断层或断裂破碎带下渗和深循环形成温泉,地热水循环深度能达到2 022.14m;温泉水循环对断裂及围岩有弱化作用,和温泉的热能释放作用一起降低了断裂和本区地震活动性。
Weihai City is rich in geothermal resources in the Jiaodong Peninsula.The Baoquantang hot spring is located in the east of Weihai City and contains a variety of trace elements and minerals.It is a hot spring of Cl-Na·Ca type controlled by the Shendaokou fault trending in NW and the Chengnanhe fault trending in EW.Atmospheric precipitation and sea water circulation are active along the fractures.The estimated circulation depth is about 2022.14 m.Due to the weakening effect of water on fault and its wall rocks,we discussed the deep circulation and energy discharge of the hot spring water and its effect to mitigate the activity of fault and earthquakes.
